BIOS Setup
3.1.7.5 Clock By Slight Adjust
This field provides several options for selecting the external sys-
tem bus clock of the processor. The available options allow you
to adjust the processor's bus clock by 1MHz increment.
If you selected an option other than the default setting and is unable
to boot up the system, there are 2 methods of booting up the
system and going back to its default setting.
Method 1:
Clear the CMOS data by setting JP3 to 2-3 On. All fields in the
BIOS Setup will automatically be set to their default settings.
Method 2:
Press the <Insert> key and power button simultaneously, then
release the power button first. Keep-on pressing the <Insert> key
until the power-on screen appears. This will allow the system to boot
according to the FSB of the processor. Now press the <Del> key
to enter the main menu of the BIOS. Select "Frequency/Voltage
Control" and set the "CPU Clock Ratio" or "Clock By Slight Ad-
just" field to its default setting or an appropriate frequency ratio
or bus clock.

Important:
Selecting an external bus clock other than the default setting
may result to the processor's or system's instability and are not
guaranteed to provide better system performance.
Note:
Use a PS/2 or AT (requires a DIN to mini DIN adapter)
keyboard for method 2.
